Operative findings in a 1.2-year-old girl with a recognizable cause of an intussusception. There are intestinal loops in the operating field; at the bottom there is the appendix and at the top a structure raised by a Babcock forceps which arises from the anti-mesenteric side of the small intestine.
It is a Meckel's diverticulum which is a remnant of the omphalomesenteric duct, observed in 1 % of the population and which leads mainly in childhood to a couple of complications; such a complication is a symptomatic intussusception, which means that the diverticulum is the seizable cause of invagination.
In the presented case an obstructive ileus has been observed due to congenital
adhesion; the adhesion between the tip of the Meckel's diverticulum and the inner side of the umbilicus was in fact a residue of the omphalomesenteric duct.
